Abstract Glucose-limited bean cells (Phaseolus vulgaris L.) were grown in a modified bacterial fermentor at a constant pH of 4.8. The cultures were kept in steady state at different specific growth rates varying from 0.00216 h−1 to 0.0106 h−1. Culture conditions are described that are needed to start a continuous culture. First, it was essential to use log-phase cells as starting material. Second, it was important to increase the dilution rate gradually, otherwise cells in the culture aggregated. Cells grown at the highest dilution rate employed contained twice as much protein per gram dry weight as cells grown at the lowest dilution rate. The composition of the cell walls also varied with the dilution rate in contrast to their relatively constant composition when grown in batch culture.
